That was posted 8 years ago, in the life of the internet, sometimes 8 days is too long for links.....the secret to finding specific information is to search that particular informational topic and ferret through all the unrelated garbage links.....if you look at the purveyors of the parrotparrot.com website, it is Rough Magic, an internet marketing firm that is apparently now using the site to post unrelated advertising (revenue producing advertising) that has nothing to do with what you were looking for...there are hundreds of thousands of those types of sites around the internet.....
